Your son came in complaining about the front end vibrating. In order to determine the cause of the vibration, we had to have it put on a lift. It could have been multiple items that caused it to vibrate.
Once it was determined by our technician that it had at least 2 separated tires and steel showing out of at least one of them, we told your son what we have found. It was determined that you wanted to put Goodyear tires on the car and you agreed to the price that was quoted. As explained, we did not have them in stock, but they were at our warehouse.
While balancing the tires, we noticed that one of the front wheels was "out of round". This would be another reason for vibration. We found a used wheel, and this price was also agreed to.
I fail to see how we took advantage of the situatiion as you state, since you as the parent, were making all of the decisions, not your son.
We did not have any "extra" charges on the ticket for us using our own tools or shop charges.
Everything was above board, with you giving the green light on all of the charges.
We work with MANY of the students in this area, espescially the Disney Intern and Sea World students, to make sure that their car is in working order. We know that some of them are far from home and the parents are not here to help them make decisions.
We are AAA approved and have been for over 20 years. It is not a certification that is easy to get and maintained.
Please have your son, stop back in when he needs his oil changed and I will make sure that he gets it free of charge.
